Abstract
To process received wireless signals received in a receiver, a noise and interference estimate is generated by subtracting the component from the received OFDM signal, a normalized noise signal by whitening the noise and interference estimate is produced, interference estimation information is computed from the normalized noise signal, a non-linear frequency domain filtering operation is performed on an output of the interference estimation to generate a frequency domain filtered signal, and a non-linear time domain filtering operation is performed on the frequency domain filtered signal to generate an estimate of an unwanted component of the received OFDM signal. The non-linear filtering may be performed using a median filter or an adaptive median filter or an adaptive hybrid median filter.
